1.	Define the term osmotic pressure. Describe how the molecular mass of a substance can be determined by a method based on measurement of osmotic pressure ?
Answer» Solution :`PI = CRT` `pi = (n)/(V)RT` `or pi V = n RT` ` or pi V = (W _(B))/(M _(B)) RT` `or M _(B) = (W_(B) RT)/(piV)` OSMOTIC pressure is INVERSELY proportional to the MOLECULAR mass of the solute.
